I am wondering, why they haven't thought about those problems before. CE certification, EMC testing, WEEE (european electronic waste regulations) are a big part of why hardware is hard. I don't know about specific regulations in the UK, but I guess they are similar to those here in germany. You can get around those regulations if your product is for use by professionals and/or for development purposes, that means there is some professional knowledge needed to make the product work (soldering, programming,...). For the rPI you only need a power adapter and a downloadable image on a SD card, thats not really professional knowledge. For CE certification, you can however put a CE badge on anything you want, and refer to some regulation (I don't have the paragraph at hand atm). This basically means "We think it will be alright". A frightening number of Chinese imports do this. This is absolutely legal, the problem comes when something bad happens, e.g. your product causes a pacemaker to fail, then you have to prove that you took all necessary precautions to prevent this, which is basically impossible if you haven't done proper EMC testing and such. Designing complex circuits (like the rPI) that do not make any EMC problems is extremely hard. I don't think most computer hardware would go through testing/certification without problems, thats why your mainboard sits in a metal case. My worst case guess is that they have to ship the boards in cases or with some shields. Disclaimer: I am a ECE student. My father is a consultant in the CE/WEEE field. Statements above are based on memorys of conversations with him, when I told him I had an idea for some hardware product (and he told me to forget it unless I want to spent a lot of money on regulatory stuff)
